1. In combination with a stove and a chimney having a flue opening communicating with a room containing the stove, a canopy supported above the stove, an exhaust cabinet open at both ends in the canopy and communicating with said flue opening, an exhaust fan in one of the open ends of the cabinet for drawing vapors from the room and delivering the same into the chimney, through the remaining open end of the cabinet, a deflector plate in the chimney, and common means for securing the cabinet and the deflector plate in their relative positions.

2. In apparatus of the character described,

' in combination with a wall having an openmg, a canopy having an opening in one end, a flange surrounding said opening and adapted to seat in the wall opening, an exhaust cabinet in the canopy adjacent the wall opening and communicating therewith, a lining in the wall opening having a flange engaging the first-named flange, bars across the opposite ends of said opening, and a bolt extended through the bars for securing the lining in the wall opening to maintain the canopy adjacent said opening.

3. In apparatus of the character described, in combination with a chimney having a flue opening, a canopy having an opening in one end, a flange surrounding said canopy opening and adapted to seat in the flue opening, an exhaust cabinet open at both ends in the canopy adjacent the flue opening and communicating therewith, at one end, a fan located adjacent said cabinet and aligned with the opposite end thereof a lining in the flue opening having a flange engaging the firstnamed flange, a deflector plate in the chimney below the flue opening, and common means for securing the lining and plate in their respective relation with the flue opening.

4. In apparatus of the characterdescribed, in combination with a chimney having an intermediate lateral flue opening, a deflector plate in the chimney having a lip extending into said opening, upwardly directed louvers in the plate to permit flow of air from the lower portion of the chimney through the plate, an exhaust cabinet open at both ends adjacent the opposite end of the flue opening, and having one of its open ends registering with said flue opening, a fan positioned at the remaining open end of said cabinet and means for securingthe exhaust cabinet and deflector relative to the flue openin 5.
